Okay now I feel like a hypocrite. I have some updating to do.

My new CX Roosters have been covering my White 3/4 Dark Cornish-1/4CX hens since 3/26/17.
My first fertile egg, laid 3 days later, hatched out on 4/20/2017.
The first chick is 10 days old and weighs 260g


For comparison, these guys are 3/4 Dark Cornish born in the same batch.




The next 4 chicks - CX roosters over 3/4DC-CX were born 4/26/17 and are 4 days old.
weights 91g, 78g, 69g, 66g
